SPTI: how to avoid installation warnings when no driver is needed?

    I have a SCSI device with the device class (peripheral device type) 0x1F =
    unknown device. The only application communicating with this device uses the
    SPTI interface. It works fine. Communication with the device doesn't require
    any additional driver to be installed.

    The only problem is that as soon as XP or Server 2003 senses the device for
    the first time it demands that a driver be installed. If I reject such a
    demand and check the "don't ask this question again" box, everything works,
    but Server 2003 pops up the Help wizard to teach how to avoid driver
    installation problems in the future.

    I tried to create an .INF file which will not actually install the driver.
    But when I do this, an annoying message pops up, saying that my driver has
    not been signed and device installation is dangerous. If I ignore the message
    and continue installation everything works fine.

    All this warnings look bad on the customer side. Is there any way to avoid
    the warnings?

    Greg,

    AFAIK no.. Ya think your problem is bad, I have a customer that has a very
    similar device, just uses SPTI, but enumerates as 16 devices.. that winds up
    being 32 clicks on NO... <sigh>

  3. is it enumerating as 16 devices on purpose? Or does it just not properly
    handle the IDENTIFY message?

    (i only ask because there's a registry hack for the latter problem, which
    causes scsiport to only probe LUN 0 if it finds a specific device ID)

    -p
